REEL FOR HARVESTER BINDERS.

- Application filed January 2 1, 1927. Serial No. 162,488.

This invention relates to the revolving reels used on harvester-binders to draw the stand ing grain towards the cutter bar. Such reels require to be adjusted both" vertically and backwards and forwards.

In narrow binders in which the reels require support at one end only, the problem of providing adjustment is a simple one, but with wide binders in which the reel must be supported at each end, difficulty is eX- perienced in bracing the bearing for the outer end of the reel shaft and in providing for its simultaneous movement with the bearing at the inner end, and our object is to devise simple and effective means for that purpose.

We attain our object by providing a bailshaped frame, on the ends of which the reel shaft is journalled. The ends of the frame intermediate its cross member and the shaft are provided with journals. At the outer end of the reel the journal is journalled in a bearing slidable on a substantially horizontal guide supported fromthe grain deck of the binder. The journal at the inner end has a bearing at the upper end of a substantially vertical swinging link. A hand lever is secured to the bail-shaped frame whereby the frame may be rocked to raise or lower the shaft or the link swung to move the frame as a whole back and forth. Means are provided to releasably lock the parts as moved.

The invention is hereinafter more fully de scribed and is illustrated in the accompanying drawings in which Fig. 1 is a plan view of our improved reel;

Fig. 2 a side elevation of the same;

Fig. 3 a front elevation of parts of'the same; and

Fig. 4 a cross sectional detail of the reel.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

1 is a part of the grain deck frame of a harvester-binder of known type. The reel 2 is provided with a shaft 3, which is carried on the ends 4 of the bail-shaped frame, formed with the cross member 5. This bail-shaped frame is pivotally supported on an axis inter mediate of the shaft 3 and the cross member 5. At its outer end the frame is'carried by a support 6 suitably secured to and braced from the outer end of the grain deck frame, and pro vided withthe substantiallyhorizontal guide? on which is adapted to slide a block 8 forming a bearing for the journal 9 extending from the bail-shaped frame behind the link 10, and at its other end to a stationary part, serves to counter balance the weight of the reel, and thus facilitates the rocking of the bail-shaped frame on its supports.

To enable the bail-shaped frame to be conveniently rocked, we secure to the end 4, adjacent the inner end of the grain deck, a hand lever 13 extending rearwardly. To hold the link in any position, to which it may be swung for the purpose of adjusting the reel, we provide the lock bar 14 pivotally connected with the link and provided with a series of notches adapted to be engaged with a keeper 15 secured to any suitable stationary part.

The end of the shaft'3, at the inner end of the grain deck, is journalled in'a yoke 16,

which is adapted to slide on the vertical guide 17 adapted to swing in a planeparallel to 1 that of the link 10. This yoke has a pinion 18 rotatably mounted thereon, through which pinion slides a square driving shaft 19 adapted to be driven in a manner common in the T art. The gear wheel 20 on the end of the shaft 3 meshes with the pinion 18. The diagonal brace 21 is secured at its rear end to the end 4 of the bail-shaped frame, and at its other end, embraces-the shaft 3.

In order that the shaft may be locked in any vertical position to which it may be moved by rocking the hand lever 13, we pro-- vide the guide 17 with holes 22, with which is adapted to engage a spring actuated sli'ding bolt 23 of known type actuable through the medium of the connecting rod 24 from the lever grip 25 fulcrumed adjacent the grip end of the hand lever 13.

From the construction described it follows that the reel may be adjusted vertically by rocking the bail-shaped frame through the medium of the hand lever 13, the frame rock ing on the upper end of the link 10 and in the bearing block 8. When the link is swung backwards or forwards to adjust the foreand-aft position of the reel, the bearing block 8 slides on the guide 7 but, at all times, adequate support is given to theouter end of the 2 reel shaft.

What We claim is: 1. A harvester-binder; a rigid bail-shaped frame; a reel shaft journalled on the ends of,

the frame; supports for the frame adapted to permit the frame to rock on an axis intermediate of its cross member and the reel shaft and to be moved back and forth; and means;

bail-shaped frame; a reel shaft ournalled on the ends of the frame; a bearing slidable on the guide aforesaid, the bail-shaped frame being jonrnalled in the bearing and in the swinging link aforesaid on an axis interme diate of the shaft and the cross member of the frame; means for locking the swinging link in any desired position Within its range; and means for looking the side of the bailshaped frame adjacent the link in any desired position When rocked on the axis aforesaid.
